A 140-Mb/s to 1.82-Gb/s Continuous-Rate Embedded Clock Receiver for Flat-Panel Displays

초록

A wide-range fast-locking embedded clock receiver, which can provide a continuous data rate of 140 Mb/s to 1.82 Gb/s in a 0.25-mu m CMOS process, is presented. A fast lock time of 7.5 mu s and a small root-mean-square jitter of 15 ps are achieved by using the proposed frequency-band selection and frequency acquisition schemes, as well as a simple linear-phase detector. The implemented embedded clock receiver occupies 2.00 mm(2) and consumes currents of 44 and 137 mA at 140 Mb/s and 1.82 Gb/s, respectively, including input/output currents.
